STACKER.

Specification of Letters Patent. Patented Oct, 12, 19 20.

' Application filed October 22, 1919.- Serial No. 332,470.

To all whom it may concern Be it known that I, GEORGE WETTLAUFER, acitizen of the United States, residing at Saginaw, in the county ofSaginaw and State of Michigan, have invented certain new and usefulImprovements in Stackers; and I do hereby declare the following to be afull. clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to pneumatic stackers and pertainsmoreparticularly to that type of pneumatic stacker which comprises anelbow that connects the air blast of a separating machine with adelivery pipe which terminates in a discharge pipe having an inner andouter telescoping section, adapted to be projected or retracted withrespect to said inner section, to increase or decrease the eifectivelength of the discharge plpe. 7

It has been customary in pneumatic stackers of this type to hinge thedischarge pipe to the delivery pipe to enable it to swing iorizontallyso that the direction of the discharge in convenient places, such asbarns or storage sheds, can be varied at will, but heretofore it hasbeen customary to adjust the length of the telescoping discharge pipeeither by moving its outer section by hand, or to effect this lengthwiseadjustment by means of chains or cables operating on pulleys, the chainsbeing arranged so that the discharge pipe could be extended ortelescoped when the hinge was closed, but it has been necessaryheretofore to remove or disconnect the chain when it was desired to openthe hinge and thereby fold the discharge pipe back upon the deliverypipe.

It is the object of my present invention to provide a simple andinexpensive means whereby the outer section of the discharge pipe may beextended or retracted, and the hinge may be bent to fold the dischargepipe back upon the delivery pipe without disorganizing the means bywhich the telescoping section is actuated.

WVith these and certain other objects in view which will appear later inthe specification, my invention comprises the devices described andclaimed and the equivalents thereof.

In the drawings, Figure 1 is a side view broken away in part, showing astacker with my mprovement attached.

F 1g. 2 is an enlarged side view, partly in section,-of the hinged endof the discharge pipe, the hinge being shown as it appears when open.

-Fig. 3 is a top plan view showing the hinged sections assembled andindicating by dotted lines the position of the delivery pipe when thehinge is open.

As is clearly shown in the drawings, 1 indicates the frame of a grainseparator, 2 the usual elbow of a pneiunatic stacker, terminating in adelivery pipe 3. Y

4 is the inner section of the discharge pipe and 5 is the outer sectionof'the discharge pipe arranged in sliding relation thereto.

The delivery pipe 3 is usually provided with a hinge member 6 and uponsection 4: of the discharge pipe is the corresponding hinge member 7,the two members enabling the pipes 3 and 4 to be opened and closed withrespect to each other, as indicated by the dotted lines in Fig. 3.

In applying my improved device for telescoping the sections 4 and 5, Imount on delivery pipe 3 and preferably on the hinge member 6 carriedthereby, a driving gear 8, and on the inner section of the dischargepipe 4C, preferably on hinge member 7 carried thereby I mount a drivengear 9 in such manner that when the hinge is closed, as shown in Fig. 1and in full lines in Fig. 3 the two gears 8 and 9 inter-mesh and whenthe sections are opened, as shown in Fig. 2 and by dotted lines in Fig.3 the gears are out of mesh.

I prefer to provide suitable means for whereby the section 5 will beprojected or retracted when the driven gear 9 is rotated by the drivinggear 8.

As one improved means for operatively connecting the gear 9 with theouter section 5 of the discharge pipe, I provide a supporting arm 13,which may be carried by the hinged member 7 and extends lengthwise thetelcscoping pipes 4 and 5. The

outer end of the arm 13 carries a sprocket 14:, on which the chain 15runs. To operate the chains 10 and 15 I prefer to provide on the gezztrs 8 and 9 respectively sprockets 16 and 1 thereby moving the chain'15so as to either project or retract the outer section 5 of thedischargeipipe. The chain '15 is preferably secured to section 5 bymeansof a 7 lug 18 fixed to a band 19 carried by the outer section 5 of thedischarge pipe.

By the means above describedl have produced a simple, yet strong andefficient device whereby the 'outer telescoping section of a hingedstacker may be actuatedwhen the stacker is closed and when the outersections of the stacker are opened by means of the hinge, thetelescoping device will be temporarily disconnected and by means of thegears 8 and 9 will be automatically connected again andput in operativeposition when the hinge isclosed.

Having thus described my invention, what I claim and desire to secure byLetters Patentisz .'j
